I am searching for the ADF2 source. On the Captain side I select ADF 2. But where ist the source? There is only one ADF Selector. Thanks for help,

There's no ADF 2 in the NGX.http://forum.avsim.net/topic/341919-how-can-i-tune-adf2/page__hl__adf2__fromsearch__1

Lot of real life NGs only have one, esp in the US. NDBs are becoming increasingly uncommon everywhere and it's pretty rare to see an approach that requires two. The actual airplane the NGX is based on only had ADF1.

Thanks, wondering that there is a ADF2 Selector.
